SAFETY ATTACHMENT FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 409,707, dated August 27, 1889. Application filed March 8, 1889. Serial No. 302,553. (No model.)

To all whom it may concern.-

Be it known thatI, RICARDO GRAsEs RIERA,

a subject of the King of Spain, residing at Barcelona, Province of Catalonia and Kingdom of Spain, have invented certain new and useful Improvements in Safety Attachments to Railway-Cars, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to devices for clearing the rails of railway-tracks of obstructions by devices attached to the car-body; and it consists of the novel devices and combinations of devices hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 represents a side elevation of one end of a car having my improvement, and Fig. 2 a longitudinal vertical section of the same. Fig. 3 is a plan of the car-axle and of the brushes, with the connecting machinery parts for driving the brushes and starting and stopping the movement of the same. Fig. 4 is an elevation of the axle and driving gearwheel thereon; and Fig. 5 is an elevation, on an enlarged scale, of one of the brush shafthangers.

Corresponding letters of reference in the several figures of the drawings designate like parts.

A denotes one of the car-axles, having mounted car-wheels B and being journaled in boxes 0 of the car-body D. Forward of this axle A are pivoted in hangers E, also secured to the car-body D, the journals of a shaft F, having rigidly mounted two circular brushes G, to be in line with car-wheels B.

Upon axle A is mounted a pinion H, and forward of this pinion H is pivoted between two hanger-bearings a another pinion I, having cranks b to the opposite ends of its shaft, which cranks are placed in a relative rectangular position, and the shaft F having formed cranks c in about its middle, also on a relative rectangular position and in line with the cranks b of pinion 1. Each crank 11 is connected with a crank c by a pitman (1, whereby the rotation of axle A is transmitted to pinion I and again to shaft F in a reversed direction.

The pinion H being loosely sleeved and feathered upon axle A, to allow lateral shifting, its hub has an annular groove engaging the forked arm 3 of a rack-bar J, horizontally and transversally secured under the car-body this rack-bar J is pivoted in hanger-boxes g g a shaft L, having mounted a pinion m, the teeth of which engage the teeth of the rackbarJ in a manner that the rotation in one dithe rack-bar J to shift the pinion E into or out of gear with pinion I. The forward overhanging end of shaft L has mounted a small miter-wheel h, engaging with a miter-wheel 2 platform dash-board of the car and provided with a hand-wheel K to its top for the conductor or driver to start or stop the movement of the brushes G.

of shaft F to enter, which slots e are curved to be concentric with pinion I. \Vith raising or lowering said shaft F it will always bedthe same distance from pinion I, and inside of shaft F is carried 011 two screw-rods 0, secured between top and bottom lugs of hanger E, to be turned by means of a wrench, said screw-rods 0 being tapped through the ends direction or another will raise or lower the bar n and therewith the shaft F, that the brushes G may be adjusted to touch the rails as they become smaller from wearing. In

hanger E has a notch 19, in which the shaft F may be supported while the brushes G are not to be used.

It will be readily seen the herein-shown deobstructions by throwing the same in a forward direction.

In place of the pitman-connection between pinion I and shaft F, an endless chain or any shaft F, with brushes G, may be thus attached under each end of the car, one or the other to be used as the car may be moved in either direction.

What I claim is 1. The combination, with a car, of a shaft pivotally suspended forward of the wheels in guide-bracketsf, to slide therein, and below 5 5 rection or another of the shaft L will move of a standard-shaft M, pivoted against the The hangers E have slots 6 for the journals these hangers E a bar 91. for supporting the of bar n, that with turning the same in one communication with the curved slot 6, each vice will clear the rails from snow or other 0 other well-known device may be used, and a thereof, and carrying circularbrushes driven fromthe car-axle to rotate in a reverse direction by tWo pinions, the one mounted upon the axle to be laterally movable thereon for shifting it in and out of gear, substantially as set forth.

2. The combination, with a car, of shaft F, carrying circular brushes an d being j ournaled in slotted hangers E and supported on bars 01, suspended on screw-rods 0 for vertical adj ustment, andof means for driving such shaft F from the car-axle in a reversed direction, substantially as set forth.

3. The combination, with a car, of shaft F,
